Eclipse plugin for editing Java resource bundles. Lets you manage all localized .properties files in one screen. Some features: sorted keys, warning icons on missing keys/values, conversion to/from Unicode, hierarchical view of keys, and more.
I use the current version 1.0.6 in Oxygen.3a Release (4.7.3a) and remember that once the editor view had scroll bars (and it should have, as it can be seen in your screenshots).
But somehow the scroll bars are missing now. Can I activate them somehow via the preferences?
